Specification of Le eters Patent.

Patented Apr. 18, 1922.

Application filed February 7, 1920. Serial No. 357,060.

f'o aiil tokio/m it may conce/ML.'

lie it known that I, iii/latini: Il. Riemann, citizen ci the United States, and a resident of i.hiiadeiphia7 Pennsylvania, have invented certain new and useful Improvements in Containers, ot which the 'i'ollo wing is a specification. 4

My invention is designed to provide a container `cr ice cream or other products7 one object or the invention being to provide a metal can which would be highly sanitary and will have a smooth interior surface throughout to prevent the lodgment oit any residue when the can is cieaned by the or dinary processes. The .interior oi the can is 'tree trom projections7 shoulders or recesses 'which would allow some oii the cream 'to lodge and become rancid and aii'cct the new charge ot cream placed in the containerl The invention is` shown in the accompanying drawing` in which l Vrepresents a sectional view oiiA the container.

Figs. 2, 2i, si, 5, and. (i are views oi portions oi a container showing lnoiliications.

In carrying out my invention, I use a main body i. of tnbuiar torni with a bottom member 2, and oi" course a suitable cover is provided 'for the upper end ot the container. The bottom member may assume different forms Within the scope ot my invention` but in the particular iorm which I have chosen in Fig. i. illustrative ot the principle embodied, in my invention, the member 2 is o't' concavo-convex ltorni with its concave face directed toward the interior et the body and this member provided with a vertical. wall. portion 3 and a 'liange 1i, which en'ibraces the lower edge of the body.j the flange 4; iitting against the outer face of the said body. The vertical portion 3 of the bottom connects With the main portion 2 oif the bottoni by a rounded edge 5. This would leave a crevice at the point where this rounded edge joins 'or contacts with the inner tace oi the cylindrical. body l, and cleaning ou the can could not be eifvtec-ted to the perfect degree as would be the case were this crevice not existing at 'this point. This crevice would allow some of the cream to lodge therein and it the cleaning ot the can Was not done With extra care, this iodgment of cream in this crevice would become rancidA and affect the new charge placed in the can. In order to prevent this l employ a supplemental bottom member 6, 'which also is of concilio-convex form and fits closely the concave face of the bottom It bridges the crevice at and bears against the inner face oi' the body at This ipiilei'nental bottom is made of a c'ompai tively thin metal but it is sufficient in thickness to provide a vertical face to get a substantial bearing against the inner tace ot the main body7 and the formation is such that a knifedike edge exists at 8, bearing against the inner `tace of the body and malo ing a close joint at this point. This supplemental bottom is secured to the main bottom in any suitable way, preferably by Welding. When the main bottom with this attached supplemental bottom is inserted in the body, the knife edge will scrape along the interior .tace of the main body and maintain a tight joint around the entire inner circumference. This joint will be covered With the tin in the operation of tinning the ran.

As above stated. the construction may assume different 'forms' and the form shown is presented in an illustrative and not in a restrictive Way the scope of my invention being defined by the appended claim.

The main liiottoin need not be in the Ytorni o'f a complete dish shaped member. but may be cut out more or less at the eentrai portionl 2X. Fig. 25 this construction providing. "however, a sutiicient flange or rim 'For the attachment oi? the complete snp plemcntal bottom thereto.

While the pars ot the bottoni can be assembled and united in various \vays i prev. 'ter to piace the main bottoni member Q iu position iirst within the body and thereafter 'tcirce the supplenientai bottinov o in troni the top oi" the body and then the main and supplementalv bottoms can be spot Welded together at about the point marked X.

Instead of attaching the main bottom niemi'ier to the body by an outside flange d as iu Fics. i and 2? I may turn a flange et* inward y and upwardly from the body to Yfan a rest for the bottom inemilier 6. as shown in liig. il. in this coi'istruction the bottoni o could be toi-ced in from the top oif the body to rest on the upper edge ot' the dang-e fi* a iter this had been turned up within the body and then the bottoni can be united with the ledge or rest altorded by the upper edge oi" the flange ix by a gas weld.

As shown in Fig. 4, a hoop or rein'lorcing bami may be en'iployed as at 4f between the upturued flange 4" and the body. This will ledge in this instance being of a width equalVv to the thickness of the-hoop plus that-.oi1 the flange el?.

This construction, like that o'lf Fig. 3,'

will` provide a smooth exterior to the lower part of the can body which will prevent drawing ice or freezing mixture 'from the freezer when the can'is lifted out, no outsideshoulde'r or edge ot the i'iange being exposed here.

ln this instance also lig. fl), the bottom and its rest or support may be secured together by a spot gas weld, after the bottom is Ytorwed intol place upon the rest, A'trom the top `ot the body.

ln all the forms above described the bottom'member is subjected to the action of dies to dish it. lt' is then blanked with the concave,- Ytace down in order to get the shearedf effect at its edge.

llhe rester supportftor the dished and lrniie edged bottom= may be afforded by a construction such as shown in Fig, 5, in which a memberslb has a 'iange turned `up both inside,- and outside. ot the lower` edge ot the body, and the bottom is welded to this. l.

Fig., 6 illustrates another modification of my invention, therchangeirom other forms pertaining mainlyl to thev use oit 'the intuined flange of thebody.

This modification illustrates they fact that tl.re.iii;tu1ned flange may be employed with a bottom. having an 11p-standing wall at 6b embraced by the said inturned flange 4f of the body.

The various forms are *presented to in- -dicate that some features of my invention are susceptible of embodiment in diiferent ways and are not indicative of equivalency as to all features involved and while the various',I forms 4have `features in common, in some degree, it is clear that some of the terms possess utility within the patent law over other forms. j

ln the vtermV shown in Fig. 6 the bottom edge of the body is widened and reinforced like that ci 7Eig. 4r, though the reinforcing characteristic is arrived at in a different way. Y

All the forms may be said to have an interior rest vfor the (lished bottom men-iber.

,lf claim:

ln combination with the main body of a can, a support withinthe lower end of the same having a portion lying adjacent the inner side olfv the wall oit' the body, and a bottom of, concave :form with its concave face presented upwardly and continued substantially uniformly to the plane of the vertical tace o'l the side edge, thereby l'orming a knife like upperA edge to'it closely against the body,n said rbottom bridging the crevice between the support and the body, and a tin coating covering the jointbetween the knife like edge and the body, said support engaging the bottom adjacent the body. the space above the joint beingv Atree for the cleaning of said joint.
